一、汇编语言和汇编程序汇编和宏汇编语言是工业测控微机系统的基本语言。即使是一个带有显示器,键盘和软硬盘驱动器的完整系统,也必须有写在ROM 或EPROM 中经过汇编的系统软件作为工具程序来支持各种接口。计算机的机器语言可看作指令的位串集合;每条机器指令能完成的动作,由计算机硬件决定。汇编语言是一种符号语言,用汇编语言编写的程序(源程 First, the assembly language and assembler assembly and macro assembly language is the basic language of industrial monitoring and control computer system. Even a complete system with a display, keyboard, and hard and soft drives must have a compilation of system software written in ROM or EPROM as a utility to support various interfaces. The machine language of a computer can be thought of as a set of bit strings of instructions; the action that each machine instruction can accomplish is up to the computer hardware. Assembly language is a symbolic language, written in assembly language (source code
